02 Simple Home Theater Guide This receiver analyzes the frequency-phase characteristics of the speakers by calibrating test signals output from the speakers with the supplied microphone, therefore flattening the analyzed frequency-phase characteristics during audio signal playback1 - the same correction is made for a pair of left and right speakers. This correction minimizes group delay between the ranges of a speaker and improves the frequency-phase characteristics across all ranges. Furthermore, the enhanced frequency-phase characteristics between channels ensure better surround sound integration for multichannel setting.2 Full Band Phase Control OFF Tweeter Midrange Woofer Group Delay Characteristics ms Hz Sound in the middle- and low-frequency ranges is delayed against the high-frequency sound due to group delay. Full Band Phase Control ON Tweeter Midrange Woofer Group Delay Characteristics ms Hz With the phase distortion corrected, the frequency-phase characteristics are improved across all ranges. • Sound with live dynamics • Sound of musical instruments with superb reality • Sound so accurately reproduced that you can even hear the lip movement of the singer • Speech heard with no loss of clarity • Surround sound with excellent integration SIGNAL SEL SLEEP DIMMER AUDIO SOURCE TV RCV SR+ SBch PHASE iPod CTRL DISP CH VOL VOL A.ATT GENRE HDMI OUT D ACCESS MCACC CLASS CH • Set the operation selector switch to RCV, then press PHASE (PHASE CONTROL) to select FULLBAND PHASE.3 Both the Phase Control and Full Band Phase Control functions are switched on. The PHASE CONTROL indicator lights on the front LCD display. Note 1 To calibrate and analyze the frequency-phase characteristics of the speakers, follow the procedures in Auto MCACC Setup (see Automatically setting up for surround sound (MCACC & Full Band Phase Control) on page 12) or FULL BAND PHASE CTRL in the System Setup (see Full Band Phase Control on page 53). Select ALL when you perform the Auto MCACC Setup with CUSTOM. Upon calibration of the frequency-phase characteristics of the speakers, the FULL BAND PHASE CTRL feature is automatically switched on. Note that FULLBAND PHASE cannot be selected unless the frequency-phase characteristics of the speakers are calibrated. 2 The original characteristics of group delay of the speakers calibrated and the targeted characteristics after correction can be displayed graphically in the OSD (see Full Band Phase Control on page 53). Also, when your PC is connected to this receiver, the original characteristics of group delay of the speakers calibrated and the corrected characteristics of group delay can be displayed in 3-dimension on your PC (see Advanced MCACC output using your PC on page 77). 3 The FULL BAND PHASE CTRL mode cannot be set to ON in the following cases: - When headphones are plugged in. - When the PURE DIRECT mode is switched on. - When the HDMI audio output parameter is set to THROUGH in Setting the Audio options on page 106. 16 En
